Mechanisms and Clinical Applications of Meridian Regulation in Acupuncture Treatment of Irritable Bowel Syndrome Based on Theory of"Meridian-Viscera Correlation"
The theory of"meridian-viscera correla-tion"explains the bidirectional relationship between the superficial meridian acupoints and the internal viscera,constituting the core content of traditional Chinese medicine(TCM)meridian theory.Physio-logical dysfunction of the viscera can be reflected on superficial acupoints through meridian conduction.When certain stimuli are applied to the body surface,the meridians can transmit information to the viscera.This theory provides theoretical support for using acupuncture to regulate meridians in the treatment of irritable bowel syndrome(IBS).The underlying pathogenesis of IBS is spleen deficiency with dampness accumulation and dysfunction of colon transmission.Acupuncture significantly alleviates and improves clinical symptoms in IBS patients by benefiting qi,invigorating the spleen,and addressing dampness to stop diarrhea.Differentiating treatment according to subtype involves selecting appropriate acupoints.Treatment strategies include soothing the liver and resolving depression strengthening the spleen and stopping diarrhea for liver-spleen disharmony,tonifying the spleen and kidney yang for spleen-kidney deficiency,and regulating cold and heat for mixed deficiency and excess syndromes.For irritable bowel syndrome with constipation(IBS-C)with lung qi failing to descend and colon obstruction,treatment focuses on promoting the dissemination of lung qi and clearing turbidity to facilitate bowel movements.Acupuncture treatment should regulate the Foot Taiyin meridian,Foot Yangming meridian,and Ren meridian,needling their respective acupoints,and additional acupoints of Foot Jueyin meridian,Foot Taiyang meridian,and Hand Taiyin meridian may be used based on individual circumstances.
